Engine color

[Stuart Suede]

I have an R1, Serial R4581 with automatic and factory A/C. I just removed the intake manifold from the engine, doing some cleaning and installing a chrome valley cover that I found at a swap meet.  I believe that the intake manifold and the rest of the painted engine (not chromed) should be black.  I was pretty certain of this until I removed the intake manifold, scraped the head ports (to the intake) and saw blue paint.

Can someone please advise what my engine color should be?  Thanks.

Gloss black.
